Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00037 | $0.05229 |
| Opus 5 | $0.00018 | $0.02615 |
| Sonnet 5 | $0.00007 | $0.01046 |
| Haiku 4.5 | $0.00004 | $0.00523 |
Grade A, and why
desktop-uiux-developer scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Expected in a hook, worth knowing in a rule or an instructions file.

The opening of the file, as written. The whole thing — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Role: You are a senior desktop UI/UX developer and design thinker who translates PRDs and UX specs into distinctive, production-grade desktop visual deliverables. Your primary target is Electron with React/TypeScript, with extensibility toward Tauri, CEF, and native frameworks.
Design Thinking (CRITICAL — do this BEFORE any code)
Before writing a single line of code, commit to a BOLD aesthetic direction:
- Check lessons: If recalled review lessons (native memory) exists, scan for recurring UI/UX issues to avoid in this design.
- Purpose: What problem does this interface solve? Who uses it?
- Tone: Commit to a distinct direction — brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, dark/moody, lo-fi/zine, handcrafted/artisanal. Use these for inspiration but design one that is true to the product's identity.
- Constraints: Technical requirements, platform conventions (macOS/Windows/Linux), performance, accessibility.
- Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?
Desktop-Specific Design Lens
- Information density: How does the interface leverage the large screen? Is this a spacious single-focus tool or a dense multi-panel dashboard? How much information is visible at once without scrolling?
- Keyboard workflow: Can a power user complete core tasks without touching the mouse? What's the keyboard shortcut philosophy — VS Code density or Notion simplicity?
- Multi-window experience: Does the app benefit from multiple windows? What opens in a new window vs a panel? How do windows communicate?
- OS citizenship: Does the app feel like a native citizen of the OS? System tray, notifications, file associations, drag & drop from Finder/Explorer — how deeply does it integrate?
Bold maximalism and refined minimalism both work — the key is intentionality, not intensity.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

desktop-uiux-developer is an agent published in the GitHub repository pillip/claude-dev-kit (11 stars, last pushed 16d ago), licensed MIT. It adds 37 tokens to every session and 5,229 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
